The merge relates to the number of segments a Lucene index holds within each shard. The force merge operation allows to reduce the number of segments by merging them. This call will block until the merge is complete. If the http connection is lost, the request will continue in the background, and any new requests will block until the previous force merge is complete. ``_ :arg index: A comma-separated list of index names; use `_all` or empty string to perform the operation on all indices :arg allow_no_indices: Whether to ignore if a wildcard indices expression resolves into no concrete indices.
